The string is currently in the form of a ByteBuffer, so we call the decode() method of StandardCharsets.UTF_8 that takes the ByteBuffer object as an argument, and at last, we convert the result to a string using toString(). In the encode() method, we pass the japaneseString, returning a ByteBuffer object.

We create a japaneseString and then call encode() of StandardCharsets.UTF_8 that is of type charsets. We can use the StandardCharsets class to encode a string to specified charset like UTF-8. String encodedString = new String(japaneseBytesArray, StandardCharsets.UTF_8) Įncode a String to UTF-8 Using StandardCharsets.UTF_8.encode and StandardCharsets.UTF_8.decode(byteBuffer) import īyte japaneseBytesArray = japaneseString.getBytes() The encodedString contains a string that is encoded with UTF-8. We use the StandardCharsets class to get the encoding charset and access the UTH_8 field. Now we create a new String using new String() and pass in two arguments, the first argument is the byte array japaneseBytesArray, and the second argument is the encoding format that we want to use. japaneseString.getBytes() returns an array of byte type. Next, we convert the string to a byte array because we cannot encode a string directly to UTF-8. We create a string japaneseString that contains Japanese characters.

We first convert the string to an array of bytes in the first method and create a string with the UTF-8 encoding.

Encode a String to UTF-8 by Converting It to Bytes Array and Using new String() UTF-8, which is short for Unicode Transformation Format - 8 bit, is a variable-width standard that assigns a different number of bytes from one to four to every code point or character.īelow we check out how to encode a string and a file’s contents to UTF-8 standard. We need to use the concept of encoding and decoding when we work with Strings, and we want to convert that string to another character set. Encode Strings From a File to UTF-8 Using Files.readString().Encode a String to UTF-8 Using StandardCharsets.UTF_8.encode and StandardCharsets.UTF_8.decode(byteBuffer).Encode a String to UTF-8 by Converting It to Bytes Array and Using new String().
